Application filed August 5, 1920.

5%" 0 all to 1 mm it mctg concern Be it known that l, CLiNroN Arvono, a citizen of the United States, residing at ll orcester. in the county of VJOZCGStGI and tltate of Massachusetts, have inventml a new and useful Color-Printing Mechanism, of which the following is a specification.

My invention relates to improvements in color printing machines for coloring warp yarns for tapestry or velvet carpets. This invention is an improvement on and an addition to that shown in my application filed August 20, 1919, and numbered 318,716 of the series of 1915, in which I show as one em-- bodiment of my invention, machine tor automatically positioning the yarn cylinder and controlling the action of the color car while all the stripes of one color called for on the design are being printed and in which the dye is then changed by hand from one to the next color. The present application shows my selective automatic mechanism for changing the colors after they have been used.

The main object of my invention is to provide an automatic machine for selectively substituting a new color tor an old one which has colored the yarn at all spots demanded by the design, and so on sari/4166777 until the yarn has been automatically dyed with many colors as the pattern requires.

further object of my invention is to provide a suitable magazine tor holding the color printing elements with their color dyes and reservoirs containing additional dye, and also to provide automatic means for actuating and positioning the magazine.

Another object of my invention is to position the color-printing mechanism while a change is made to a new color.

Another object oi my invention is to keep the yarn support from moving during the time on: color change. 7

Another object of my invention is to pro vide automatic devices for wiping the scrapel'S when a new color is placed in the colorprinting mechanism.

Another object of my invention is to position a color supply container and transfer color from it at predetermined intervals to the color printing mechanism.

Still a further object of my invention is to prevent the color printing mechanism Specification of Letters Patent.

In the drawings which are merely illustrative of my mechanism all the parts of my invention are disclosed.

My device is made in this particular instance as an attachment to the standard manually operated printing drum and the various brac rets and bearing attach to and are supported by the regular drum frame of the machines in common use in t country and England in which will be found the usual yarn cylinder, means for winding the yarn thereonto color-car and the operating means therefor, etc, and the use or my invention makes such a machine an automatic one. 1 is the yarn cylinder turnfreely on its axis when driven by the altar pulley 2, and associated gearing. Various skeins of yarn 3 are on spools 4 and are respectively mounted freely on spindles 5. The yarn 8 passes upward. from the spools i through the yarn guides 6 to the cylinder and the end of each skein of yarn is made fast thereonto so that when the cylinder is revolved the various skeins will be wound thereupon preparatory to being colored. The guides 6 are attached to the bar 7, which by means of the rack 8 in mesh with the gear 9 is caused to move slowly across the face of the cylinder by suitable gearing as in usual practice so as to lay the bights or coils of yarn side by side one deep ever the surface thereof the terminal end of one skein meeting the initial point of its neighbor skein. A certain degree of tension is imparted to the yarn by means of the friction pads 10 which are pressed against the yarn on the spools i by the action of weights 11 and thus the yarn is laid smoothly and somewhat snugly on the cylinder so as to present a suitable surface for the coloring operation. The rear ends of the skeins are attached to the cylinder as soon as the winding is completed as in regular practice.

The cylindc 1 is equipped with an internal annilar gear 12 made fast thereto by the stands 13 (Figs. 27 and 1) and a gear 14% fast on she. t 15 meshes with the teeth of Shaft 5 turns freely in bearing (Fig. 2) and in the manually operated nting drums in common use a hand wheel is made fas to the other end of shaft 15 so that the operative can place the yarn cylinder 1 in any desired annular position by turning the hand wheel and he is kept constantly employed doing this and operating the printing mechanism.

1 substitute a jacquard machine with its perforated strip in place of the operative and will now describe my new mechanism for the selective automatic positioning of the yarn cylinder 1 the control of the printing of the yarn the placing of the different colors, etc.

The jacquard is indicated by the perforated strip 16 which feeds over the cylinder 17 in the conventional manner, and acts on is therefore raisen so tiiat the end .33 el vated up over the orn e :cs an operative stroke to tho iac g 1rd cylinder 17 is up ctiiis; the ends of the hooks l' continues a forces toward the left t t have not been raised abo e he 2i ilc the hooks have ll not be moved by the all those hooks 19 l i raised like 19 w].

do); wheel 27 is pro ided with an 0:;-

hub 87 upon which is fastened the -ear 38 which meshes with spiral gear hand wheel shaft i5, (Figv 27).

a re ating: rioveinent imparted to index will move yarn cylinder 1, the modescribe how at "oniatic nio- .iipartee to my index wheel 2'! which linden pawl leonly nniunted on the extended hub the index wheel. and next to the tchet 28 and at its outer end is freely athcd the pawl ll on the fulcrum pin 42 good to work with the ratchet teeth of the wheel. The spring causes 1 click sharply into the teeth of The pawl lever to is provided with the rib which is located opposite the circle o pins in the index wheel and extends close up to the face 36 through which the pins 30 are projected by the jacquard hooks back of the rib set, and the protriulinp pins act in turn as checks against the rearward movement of the pawl lever and when rib 1- is in Contact w i a pin the pawl clicks operly into the c espondinp; ratchet tootl The motion of the pawl lever e310 forwardly about the hub 37 is directly hinited by he dead stop ilianil indirectly reamvardly by the dead stop 46, the total vernent being a little more than a circle, or about twenty-four and t woe-qua rters ratchet teeth.

The pawl lever 40 is retracted by the pull of the band 47 attached to the hub of pawl lever 40 at 48 (Fig. 28) for the weight 49 attached to the other end of the band, hence after an operative stroke the pawl is automatically retracted until arrested indirectly by dead stop 16, or directly by a protruded pin 30, The working; stroke of the pawl is caused by the pusher finger 50 which contacts on the boss 51 of the pawl lever 40 and urges the lever forward until checked by the dead sto L5 as clearly shown in Figs. 28 and 29. The pusher linger 50 is attached to the arm 52 which has the hub 53 (Fig. 29) journaled freelyon the hub 37 of the index wheel. Spur gear 5% is firmly attached to pusl hub 53 and meshes with rack 55, the rod head 55 of which is pivoted on the crank stud 56 of crank arm 57 which is reyed fast to shaft 57 revolving in suitable hearings and which receives a fast and slow motion from the constantly rotating shaft 58 by rneans of the sector gears 59 and driven independently of the index and which lOO operates the index. These sector gears are so timed as to make the crank stud 56 receive its working stroke in slow time while its return stroke is made in almost one-half the same period of time oscillates once each way for one revolution of the crank arm 56. The crank 57 revolves twice to one revolution of the constantly revolving shaft 58. The sweep of the pusher finger around its axis, which of course coincides with the axis of the index wheel 27, is a little greater than the full sweep of the pawl lever 40. When the rib 44 of the lever 40 is in contact with a protruding pin 30 the pusher will make a partial idle forward stroke until it comes in contact with lug 51 and will then proceed to drive the index pawl lever forward to the dead stop 45. The index wheel is always rotated forwardly by a movement oi the pawl 41, and the degree of angularity of this movement is determined by the distance the pawl 41 moves backward until checked. The shortest operative stroke of the pawl covers a distance equal to but one tooth oi the ratchet 27, and the greatest stroke includes twenty-four teeth of the ratchet; and the ratio of the communicating gears is such that a move of one ratchet tooth causes a corresponding movement in the yarn cylinder equal to the passage of a color stripe, therefore my index wheel will cause the yarn cylinder to be turned tooth by tooth, or in skips up to twenty-tour teeth, just as does the hand of the operative upon the hand wheel of the ordinary machine. My index wheel takes the place of the opera tive and his hand wheel, turning the yarn cylinder in the proper time, and holding it at rest for the requisite periods just as does the operative in the well known hand controlled machine.

Spiral gear 38 is equipped with a brake drum 61 (Fig. 1) over which can pass a suitable conventional friction band to cause suilicient drag to prevent the index wheel from running away from the pawl 41 and assures that the cylinder comes to rest at the proper angular spacings.

I will now describe how the rib 44 of the index pawl lever 40 on its retraction gets past the jacquard protruded pin that checked the rib. There is an imaginary line passing through the center of the axis of the index wheel called the zero line and this line is marked X-X on Fig. 27. The center of the pivot pin 42 of the index pawl 41 coincides with the zero position or X-X line when the pawl lever is checked by the front dead stop 45. as illustrated by Fig. 27. Fast to plate 24 is the retracting cam 63 (Figs. 18 and 19) which is so located near line X-X that the head 31 of any jacquard protruded pin 30 will contact this cam just after the index wheel passes the location of the end 32 of the jacquard hook 19 that is located immediately back from the zero point and the continued forward movement or" the index wheel for the single space up to Zero will cause the contacting pin to be cainmed back, or retracted, into inoperative position as regards the index pawl lever.

The rib 44 of pawl lever 40 is now tree of the pin immediately back of it, and against which it had stopped, and the weight 48 retracts the pawl lever and it "follows the retreating pusher until rib 44 comes in contact with another protruded pin, or until the lever is checked by the rear dead stop 46. Thus the acquard projected pins 30 are retracted whenever they pass the Zero point, so that one complete rotation of the index wheel will cause every projected pin to be retracted by the cam In the circle of pins 30 on the disk is a spring actuated pin which is projectec. by the flat spring and this pin is likewise retracted by the cam 63. As it is protruded by the spring it is called the spring pin and as soon as it passes cam 63 i.t is forced out beyond the face 36 of the index wheel by action of the sprlng 64 and consequently the rib 44 always comes in contact with this spring pin and tie index pawl lever always stops against Thus whenever the pawl lever is checked rearwardly by the spring pin the pusher will upon its next operative stroke bring the spring pin to the zero point.

The jacquard is timed toindicate and protrude the pins 30 at this point; 2'. e. the spring pin 64 is retracted being at zero and its head 31 is resting on the cam 63 and in th1s position all the other forty-seven pins 30 inthe circle are each located opposite the working end 32 of a jacquard hook 19.

Spring pin 64 is not projected bv a jacquard hook for its office is to assure that the int ex wheel always stops with the spring pm at zero so that the pins in the wheel can be set up anew by the jacquard. Thus the predetermined lay-out oi the perforations in the jacquard strip 16 will automatically determine the annular movements of the yarn cylinder 1.

I will now describe the method of printing the yarn and show how my devices auto matically control the coloring of the yarn.

As shown in 14 a hub 65 is spl'ined fast on shaft 58 so as to rotate therewith. J JlRP ICCl turn about and upon hub 65 is the hub 66 carrying the crank arm 67. The shaft 58 1.(" 5l-.'8S its motion from pulley 2 shown in 1 and 3 through the pinion gear 69 meshed with gear 70 which is fast on shaft The hub 66 is formed at diametrically opposite points with the semicirrular r cesses ic A locking bolt 71 is trunnioned partially in the hub 65 and partially in the hub 66 as shown in Figs. 13 and 15 and it operates in a manner similar to the well known power punch press control.

The bolt 71 is cut away as at 72 where it extends into the hub that is fast on shaft The lockingbolt 71 is adapted to be rotated. in its seat in the hub and into the recess bored in the hub 65 as shown in Fig. 13. The gear 7 is fast on the locking bolt 71 and serves to es late the locking}; bolt, this meshing with tl a gear it which is pivoted on the stud 75, mounted in one of two d ametrically opposed lugs 76 formed upon the crank hub 66. An ainiiting' arm 77 teri'ninating in a pawl 78 is pivoted on stud and another similar abutting arm is pivoted on stud T9 diametricall opposite the one on stud 75. The ear 74: has a crank arm 80 which is pivotaily connected by a connecting rod 81 to hi abutting arm mounted onthe stud The spring); 82 is secured at one point to the crank hub and also to the connecting rod 51 shown in Fig. 13. The spring normally holds the two abutting arn s in the positions indicated in the term oi? the broken line pawls 78 in 13, this position of one of the abutting arms being: shown in F iii, whereupon it willbenoticed. hat the locking; bolt 71 has been rotated in its t and into the recess bored in Hi6 hub 5 shown in 15, and in that position it crank arm 6'? to rotate in unison with the shaft 58. revolving crank stud 83 con n is this crank arm 6? with a stroking arm 84- carrying a rack at its lower end (Figs. 3 and 36) this raclr meshing with a sector near 86' which in turn meshes with the secured to shaft .87 which also aft so that the oil? the cords, being attached to the color-oar in the usual manner ill impart motion to the color car whereby it will be stroked l l: and forth. will be noticed that the re: g arm 90 fulcruins on the axis 91 ot the se=tor gear so to carry the rash into engagement with the sector gear in-s. 2. and

Th iec uard sets up or registers the pins inden wheel according to the design ii l pawl moves the ratchet oi the int l6 selachordingly as its level impacts in its ward motion agch st the va ious protrndiugr pins, the pa me are teeth around the circumferen e of l srn cylinder. so it may be necessary to turn the index wheel one or more t mes to reoister the intervals apart between which coior stripes are to be applied to the yarn on the drum. in other words the cylinder may have to make several moves before it comes to rest to receive a color stripe. In this event it will be necessary to prevent the premature operation of the color applying mechanism furnished by the color car. The range of movement of the pawl 43. covers twenty-four ratchet teeth or practically one-' half of the total number of teeth on this index wheel; therefore any pin 30 projected opposite any oi those 24 teeth assures that pawl ti will turn the index wheel and consequently the drum a similar number of teeth. [is this takes place the color car is running back and forth on its track applya color stripe to the yarn whenever the drum has ceased to rotate. So far the mechanism described is adapted to enable the cylinder to move over distances representing intervals up to 24: teeth one half a revolution of the ratchet-wheel. I may, however, be necessary to more the drum or cylinder over a greater distance. This being beyond the power of the pawl lever 40 to accomplish by a single stroke it will. be necessary for it to make a double or duplicate stroke, the drum during; this event. making two correspending moves and therefore stopping twice, as it stops during each back stroke of the pawl lever 10. H wever as the col0rcar strokes the yarn of the drum every time the drum stops it willbe necessary to cut out tie latters operation. during the first stop of the drum and immediately reactuate it when the drum makes its second stop after having moved over the required distance, because the requirements of the carpet de sign has called for this larger ship of the ratchet wheel.

The mechanism required to stop the movement f the color car must operate in such a manner that the color-car will be stopped for as long a time as required in position representing either extreme 03"? its movement where it will be out of contact with the drum. .t is necessary to cause some imped'nent or check to operate to arrest the movement of crank arm t rouo'h the shut- O! o ting arm 78 atter the color motion has made a scheduled number of mpressions. To eftect this result I provide a primary and a subsidiary color control device consist ng: of a hell cranl: lever 92 (Figs. 2, 3. and 27) fulcrumed on stud 93 and having one arm 92 held slightly above the dead stop 4L6 by means ot the spring 94. while its other arm is pivotally connected the connecting rod 96 the other end of which is connected to the lever 97 fulcrumed at 98 and provided with a cain'end or portion 99 shown in Figs. 27 and. 29, this cam end adapted to bear against a cam 100 on the arm 101 the lever 102 fulcrumed intermediate its ends upon
